| // the default implementation of publicRequirement() having the |
| // wrong linkage. |
| // |
| // It should be 'shared [fragile]', but it's not clear that this |
| // this makes sense either, because 'R' is private. |
| |
| // Perhaps the conformance S : R should be rejected, because |
| // publicRequirement() is not sufficiently visible; furthermore, |
| // the use of the 'public' keyword inside an extension of 'R' |
| // should generate a warning, since it has no effect. |
